Abstract The effectiveness of a sex pheromone trap designed specifically to deliver conidia (infective fungal propagules) of the entomopathogenic fungus Zoophthora radicans Brefeld (Zygomycetes: Entomophthorales) to male Plutella xylostella (Linnaeus) was investigated. In field experiments in the Cameron Highlands of Malaysia, synthetic pheromone lures attracted adult males P. xylostella at all times of the day whereas lures of virgin female moths attracted males only between the hours of dusk and dawn, when females are known to produce their pheromone. Adult male moths attracted to traps baited with synthetic pheromone spent a geometric mean time of 88 seconds within the inoculation chamber, a time compatible with the period adults must spend within a shower of Z. radicans conidia produced by uniform mycelial mats in order to become infected. The field longevity of male and female P. xylostella adults was found to be similar, with individuals living for a mean time of 4.9 days. This was sufficient time for male moths to respond to the pheromone, enter the trap, become infected with Z. radicans and succumb to that infection in the field (3-3.5 days) thereby releasing infective conidia into the cabbage crop.
